Fig. 8 is a vertical cross-section through the roof seam on'line 8,8 in Fig. 7. p

Referring to Figs. 1' to 4, inclusive, of the accompanying drawings, my invention is shown in connection with the radial all-steel flexible car roof comprising angle bar side plates 10 that are connected by carlines 11 of substantially inverted channel shaped section with outwardly projecting base. flanges 12 at the bottoms of theirside walls. The angle bar side plates 10 are preferably arranged with one flange vertical and with the other flange disposed uppermost and ex tending outwardly horizontally. The eaves end portions of the carlines rest flatwise on the outstanding upper flanges of the side plates and have their flanges riveted or otherwise rigidly secured thereto.

Full length metal roof sheets 13 of rela tively light gage extend from eaves to eaves between carlines and are supported at their eaves ends on woodenfiller strips 14. which extend fronrcarline to carline and are bolted 'or otherwise rigidly securedto the outstanding top flanges of the side plates 10. The roof sheets 13 are supported on the filler strips 14 above the plane of the lateral base flanges 12 of the carlines 11 and have upwardly offset marginal portions 15'that are inclinedupwardly and terminate in side marginal flanges 16 that extend from end to end of the sheets and arenormally spaced away from the sides of the body portions of the carlines. The roof sheets 13 are also provided at their eaves ends with depending flanges 17 thatoverhang and are normally spaced from the outer edges of the wooden filler strips 1 1 and the side plates 10.

l/Veatherproofing members inthe form of inverted channel shaped seam covers or caps A straddle adjacent side marginal flanges 1.6 of the roof sheets and portionsof the carlines located th'erebetween, the inside width of the seam covers being sufficient to leave a space between each side wall thereof and said adjacent marginal seam flanges 16. The 'webs or tops of thechannel-shaped seam covers bear flatwise a ainst the websor tops of the channel-shapedcarlines 11 andare riveted or end to end (it the' cur.

tifi

ove res otherwise rigidly secured thereto. The chansagging oil the sheets between side plates by nel-shaped seam covers are provided along the lower edges of their side walls with outstanding base flanges 18 that rest or bear flatwise on the inclined side marginal portions of adjacent root sheets and thus serve to hold said sheets down on the car. The eaves end portions of the seam caps are provided with depending eaves flanges 19 which cover the open ends of the carlines and the eaves corners of adjacent sheets and are normally spaced away from the latter. The transverse seam caps A are preferably made in three sections: namely, duplicate end members or sections 20 which extend from theeaves to points adjacent to the ridge, and a single intermediate or ridge Section 21, which overlaps the ridge end portions of the two end sections for a suitable distance on each. side 01. the ridge. The ridge section of each sean'i cap pressed outwardly adjacent to each end, as at 22, to ,JiOVltlG space between the overlapping portions of the ridge and end sectio s tor strips oi tar paper or other suitable material 23 which is dipped in paint before application.

Running boards 24; extend longitudinally from the car at the ridge and are supported on the lateral top flanges of Z-bar running board saddles whose lateral base flanges rest on the ridge sections 20 ot the seam caps hand are rigidly secured thereto by the rivets that secure the ridge portions of the caps to the cal-lines. i In order to insul "e the above root against heat and to cliinii sweating or condensation oi moisture on inc undersurfacc of the root sheets and carlines, said root is provided with an insulating lining B which e: tends from side plate to side plate and from showi'i in Figs. 1 to 4;, inclusive, said lii'iing comprises matched or tongue and groove .heathing boards 26 which extend loi'igitud .ally of: the car beneath the carliues and roof sheets and insulates the underside of the entire roof. The

sheathing boards are long enough to span the spaces between two or more car-lines; and each board is preferably bolted or otherwise rigidly secured-to the undersides of one of the outstanding base flanges 12 of every other carline 11 by bolts 27.

As stated above, the root sheets are sup-- ported on the woodei'i eaves tiller strips 14 above the plane of the lateral baseflanges 12 ot the carlines 11 and the root lining B is disposed beneath the car-lines, thereby forming a dead air space 28 between said. root" sheets and said lining which serves as a heat iusulatorf As shown in the drawing, the sheets are supported intermediate their eaves ends by means of wrmden filler strips 29, which extend longitudinally of the car between cal-lines and rest on and are nailed. to the root lining. The strips 29 prevent reducing the span which the sheets have to bridge, thereby increasing the load carrying capacity of said sheets, maintaining a heat insulating space of uniform depth between the sheets and the roof lining B.

Among the advantages of the above construction arc'its great simplicity and cheapness and the ease with which it may be applied. to or removed from the root after it has been placed on thehcai'z. It is particularly noted that the above construction forms a continuous insulating lining, beneath the roof sheets and the carlines from eaves to caves and from e id to end of the car.

The construct-ion shown in Figs-5 and 6 has the same arrangement oi? side plates, carl-ines and seam covers; but the lining boards 30 extend transversely of the car and are supported at the ridge on a ridge pole 31, intermediate the ridge and eaves on purlins 32, and at the eaves'in the rabbeted inner edges of wooden filler strips 33 which rest on the side plates. As shown in the: drawing, the rooi sheets are spaced above the roof lining and car-lines, at the ridge, at the caves, and intermediate the ridge and eaves by filler strips 33, which are secured to the tops oi": the ridge pole 31, purlins 32 and eaves strips 33 and extend longitudinally thereof between carlines. The ridge pole and purlins are bolted to the undersides oi the base flanges of the carlines; and the lining boards 30 are arranged in two panels on opposite sides of the ridge, the boards which span the spaces between the ridge pole 31 and purlins 32 being, disposed with their ends in abutting relation to the spacing strips supported thereon, and the boards which span thespaces between the purlins and the eaves strips 33 being disposed with their ends in abutting relation to thespacing strips on the purlins and said eaves strip' Figs. 7 and 3 show a construction wherein the roof sheets are supported atthe eaves on a filler strip 34, which rests on the horizontal web of Z-bar side plate 35 and is bolted to the upstanding inner flange thereof. The sheets are supported intermediate their eaves ends on a ridge pole 36 and purlins 37 bolted to the base flanges 12 01 the carlines 11 and the insulating lining comp-rises sheathing Hill boards 38, which extend longitudinally of the car between the ridge pole 36 and purlins 37 and between the latter and the side plates and are nailed or otherwise secured to the bottom surfaces of wooden filler strips 38 that fit Within the downwardly opening channels of the inverted CllL-llIlGl-SllLIMCl carlines 11 and are bolted thereto. The car: line fillers 38 extend below the lateral flanges 12 of the carlines 11 and thus serve to space the insulating lining below the body of the sheets. As shown in Fig. 7, the carlines 11 are secured to said plate 35 by angle-shaped car-line brackets 39', having one flange bolted fiatwise to the undersides of the carlines and side of said brackets, the bolts extending through said bracket and the base flanges of the carlines. As the carline filler strips 38 are primarily int-ended as nailing strips for supporting the lining between the ridge pole and purlins' and between the latter and the oarline brackets, said strips are preferably made in four sections, the inner sections ex tending from the ridge and terminating short of the p-urlins and the outer sections extending between the purlins and the carline brackets and terminating short thereof.

This invention is not limited to the pie 'cise shapes and arrangements of parts shown and described.
